Abstract
Computer apparatus for assisting the reading of a document by displaying upon it a chronologic sequence of pointing gestures, comprises a camera and data processor for imaging the document and for tracking the movement of a pointer, such as a person'"'"'s finger, over the document to associate that movement with the imaged document as the said sequence, and a computer with a projector for displaying the sequence in association with a reproduction of the same document, which may be printed paper or an on-screen image, normally at a remote location for conferencing.
A photograph on a two dimensional medium comprises a computer-readable representation of such a chronologic sequence of pointing gestures associated with the photograph.
